Nice try, really
That being said, this is nowhere near a classis either.
The good: quite asonishing production value; good overall mechanic design, at least theoretically; amazing video/audio presentation; unique.
The bad: quite short in length; numerous stage design flaws; frustrating combat; pretty poor pacing.
Ok, now here's what I think:
Watching (well, playing, really) this game makes me feel pretty sad. With an amazing style and visual design, adding up with a more than solid production value, this game has an amazing potential to be great. The main flaw here lies on the game's machenic.
The game incorporates three elements: running, puzzles, and combats.
Running is a blast, but you are often left wondering where exactly to go, even with the "red-hint" system.
Puzzles are paces too slow, and there are some minor design flaws with the interior climbing sequence, especially since this is a first-person game.
Combat, on the other hand, is great in theory, but really not satisfying. The enemies are placed so that it is impossible to fight them without stopping and taking cover. They gun you down quickly, and at the last few stages you will be coursing when you see the must-fight red enemies.
Overall, I consider this game an opportunity missed for making a classic. That being said, it is definately a game worth checking out. Since it's short, rent the game would satisfy most people. Honestly, tho, when I see this game, I see a wasted porduction value being tripped up by minor flaws. It's sad, really
